Product Description
Molex 39-28-8220 Mini-Fit Jr Series Straight Through Hole PCB Header is a high-quality 22-contact connector designed for reliable power connections on printed circuit boards. Featuring a 4.2 mm pitch and 2 rows with a shrouded, scoop-proof nylon housing, it ensures durability and secure mating in demanding electrical environments.
This PCB header supports up to 6A current per circuit, suitable for high power and high-density wire-to-board applications. The brass contacts with tin plating provide excellent conductivity and corrosion resistance, while fully isolated terminals reduce the risk of arcing and debris interference.
Designed with polarization and keying features, the connector prevents misalignment and mismating with the corresponding receptacle. The positive locking mechanism secures the connection and provides an audible click to confirm full mating, preventing accidental disconnection due to vibration or shock.
The through-hole mounting type facilitates strong and permanent soldered connections to the PCB. Operating temperature range from -40°C to 105°C ensures suitability for various industrial, consumer electronics, office equipment, network, and server applications.
Additional features include availability with snap-in PCB retention pegs or mounting flanges for enhanced mechanical stability. The Mini-Fit Jr connectors are widely used in industrial automation, rack-mount servers, routers, switches, consumer white goods, and other high-density power applications.
